Chromatica
''Chromatica'' is the sixth studio album by American singer Lady Gaga, released on May 29, 2020, by Interscope Records and subsidiary Streamline. Gaga supervised the production with longtime collaborator BloodPop and a variety of other producers to create a concept album returning to her dance-pop roots, eschewing the stripped-down style of its predecessors '' Joanne'' (2016) and '' A Star Is Born'' (2018). ''Chromatica'' draws inspiration from early 1990s house music, seeing Gaga adopt a cyberpunk-inspired persona. The album centers on ideas of unwavering happiness and the pursuit of healing. Songs on ''Chromatica'' encompass themes inspired by failed romance and mental health struggles in Gaga's private life. The music is distinguished by dense synthesizers, percussion, grooves, and orchestral arrangements that merge overarching melodies. Blackpink, Ariana Grande, and Elton John contribute guest vocals. Most of the recording took place at Henson Recording Studios and Gaga's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARP Chroma
The ARP Chroma is a polyphonic, multitimbral, microprocessor controlled, subtractive synthesis analog synthesizer developed in 1979-1980 by ARP Instruments, Inc. just before the company's bankruptcy and collapse in 1981. The design was purchased by CBS Musical Instruments and put into production by their Rhodes Division in 1982 as the Rhodes Chroma at a list price of US $5295. They also released a keyboard-less version of the Chroma called the Chroma Expander at a list price of US $3150. The Chroma was one of the early microprocessor-controlled analog synthesizers. It was designed before MIDI and featured a 25-pin D-sub connector computer interface used to slave the Expander to the Chroma. Also, an Apple IIe interface card and sequencing software was available. The Rhodes Chroma and Expander were discontinued in 1984. Somewhere between 1400 and 3000 Chromas and Expanders were built. Keyboard velocity and pressure The Chroma has a velocity-sensitive keyboard consisting of 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorfulness
Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity. As defined formally by the International Commission on Illumination (CIE) they respectively describe three different aspects of chromatic intensity, but the terms are often used loosely and interchangeably in contexts where these aspects are not clearly distinguished. The precise meanings of the terms vary by what other functions they are dependent on. * Colorfulness is the "attribute of a visual perception according to which the perceived color of an area appears to be more or less chromatic"., page 87. The colorfulness evoked by an object depends not only on its spectral reflectance but also on the strength of the illumination, and increases with the latter unless the brightness is very high ( Hunt effect). * Chroma is the "colorfulness of an area judged as a proportion of the brightness of a similarly illuminated area that appears white or highly transmitting". As a resu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chroma Feature
In Western music, the term ''chroma feature'' or ''chromagram'' closely relates to twelve different pitch classes. Chroma-based features, which are also referred to as "Harmonic pitch class profiles, pitch class profiles", are a powerful tool for analyzing music whose pitches can be meaningfully categorized (often into twelve categories) and whose tuning approximates to the Equal temperament, equal-tempered scale. One main property of chroma features is that they capture harmonic and melodic characteristics of music, while being robust to changes in timbre and instrumentation. Definition The underlying observation is that humans perceive two musical pitches as similar in color if they differ by an octave. Based on this observation, a pitch can be separated into two components, which are referred to as ''tone height'' and ''chroma''. Assuming the Equal temperament, equal-tempered scale, one considers twelve chroma values represented by the set : that consists of the twelve pitc ...

Chroma Key
Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two images or video streams together based on colour hues ( chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture, and video game industries. A colour range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as colour keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific colour-related variants such as green screen or blue screen; chroma keying can be done with backgrounds of any colour that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most di ...

Munsell Color System
In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), chroma (color intensity), and value ( lightness). It was created by Professor Albert H. Munsell in the first decade of the 20th century and adopted by the United States Department of Agriculture (USDA) as the official color system for soil research in the 1930s. Several earlier color order systems had placed colors into a three-dimensional color solid of one form or another, but Munsell was the first to separate hue, value, and chroma into perceptually uniform and independent dimensions, and he was the first to illustrate the colors systematically in three-dimensional space. Munsell's system, particularly the later renotations, is based on rigorous measurements of human subjects' visual responses to color, putting it on a firm experimental scientific basis. Because of this basis in human visual perception, Munsell's system has outlasted its c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chroma (album)
''Chroma'' is the debut studio album by the American rock band Cartel. Formed in mid-2003, they self-released an EP the following year.

Enchroma
EnChroma lenses are a brand of color correcting glasses designed to alleviate symptoms of red–green color blindness. Studies have shown that while the lenses alter the perception of already perceived colors, they do not restore normal color vision. Initial claims in excess of this by the manufacturer have been criticised and characterized as marketing hype. Recent research has shown the lenses have a positive impact on those with red-green color blindness. History Glass scientist Donald McPherson invented EnChroma glasses by accident. He originally was trying to develop lenses to protect and aid surgeons during laser operations. Technology The lenses focus on the most common color vision deficiency which is caused by the red and green retinal cone cells that, when responding to light, coincide. To eliminate the overlapping of the wavelengths of light, there is an optical material called a notch filter, which is capable of removing the exact wavelengths of light in the l ...

Chrominance
Chrominance (''chroma'' or ''C'' for short) is the signal used in video systems to convey the color information of the picture (see YUV color model), separately from the accompanying luma signal (or Y' for short). Chrominance is usually represented as two color-difference components: U = B′ − Y′ (blue − luma) and V = R′ − Y′ (red − luma). Each of these difference components may have scale factors and offsets applied to it, as specified by the applicable video standard. In composite video signals, the U and V signals modulate a color subcarrier signal, and the result is referred to as the chrominance signal; the phase and amplitude of this modulated chrominance signal correspond approximately to the hue and saturation of the color. In digital-video and still-image color spaces such as Y′CbCr, the luma and chrominance components are digital sample values. Separating RGB color signals into luma and ...
